LM8262 Dual RRIO, High Output Current & Unlimited Cap Load Op Amp in MSOP
LM8262 Dual RRIO, High Output Current & Unlimited Cap Load Op Amp in MSOP
June 2002

General Description

The LM8262 is a Rail-to-Rail input and output Op Amp which can operate with a wide supply voltage range. This device has high output current drive, greater than Rail-to-Rail input common mode voltage range, unlimited capacitive load drive capability, and provides tested and guaranteed high speed and slew rate. It is specifically designed to handle the re­quirements of flat panel TFT panel V as well as being suitable for other low power, and medium speed applications which require ease of use and enhanced performance over existing devices.
Greater than Rail-to-Rail input common mode voltage range with 50dB of Common Mode Rejection, allows high side and low side sensing, among many applications, without having any concerns over exceeding the range and no compromise in accuracy. In addition, most device parameters are insen­sitive to power supply variations; this design enhancement is yet another step in simplifying its usage. The output stage has low distortion (0.05% THD+N) and can supply a respect­able amount of current (15mA) with minimal headroom from either rail (300mV).
The LM8262 is offered in the space saving MSOP package.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Rating indicate conditions for which the device is
LM8262
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5kin series with 100pF.
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
Note 4: The maximum power dissipation is a function of T P
=(TJ(max) - TA)/ θJA. All numbers apply for packages soldered directly onto a PC board.
D
Note 5: Typical Values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: Positive current corresponds to current flowing into the device.
Note 8: Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.
Note 9: Machine Model, 0is series with 200pF.
Note 10: Short circuit test is a momentary test. See Note 11.
Note 11: Output short circuit duration is infinite for V
Note 12: Offset voltage average drift determined by dividing the change in V
